Det ironiske er at jeg kan åbne en virtuel maskine fra ubuntu og tilkoble usb-drevet der og tilgå det uden problemer.
Jeg har tidligere haft mount problemer af en lidt anden karakter. Jeg lavede for nylig en ændring til min /etc/default/grub med at tilføje ACPI=off et sted. Det løste problemerne og den kørte problemfrit i en uge, men nu er den altså noget galt igen.
Jeg kan ikke se drevet blive mountet i "Maskine"-mappen. Jeg kan derimod godt finde nogen af mapperne/drevene i /media, men de tilhører root og fremstår i øvrigt som tomme når jeg browser dem med nautilus som root (jeg kan ikke få adgang hvis jeg ikke er root).
Er der nogen der kender til problemet eller kan gennemskue hvad det går ud på?
PS: Jeg vil lige forsøge at boote på en ældre kernel. Så skal jeg melde tilbage.
EDIT 1: Jeg har lige prøvet at nedgradere og låse den version af gnome-disk-utilty der var blevet installeret fra en ppa, den dag det holdt op med at virke. Det lod heller ikke til at have nogen effekt.
EDIT 2: Så har jeg test på en tidligere kernel 2.6.31-17-generic og er tilbage på 2.6.31-19-generic. Det virker desværre ikke på nogen af dem.
Jeg har opdaget en segfault i kernel-loggen.
Feb 25 18:35:25 lars-desktop kernel: [ 143.409026] gvfs-gdu-volume[3622]: segfault at 18 ip 00007fec3f90fc70 sp 00007ffff91caf28 error 4 in libgdu.so.0.0.0[7fec3f8fa000+37000]

Det ser egentlig lidt besynderligt ud.
EDIT 3: Jeg får da godt nok fejl på alt lige nu. Hvis jeg prøver at starte palimpsest (system->administration->diskredskab får jeg følgende i kernel-loggen:
Med hensyn til mapperne i /media som jo skulle gøre det ud for mountede drev, så bliver de der uanset om drevet om drevet er tilsluttet eller ej - ja selv hvis jeg laver et frisk boot uden drevet er de der.Feb 25 18:55:37 lars-desktop kernel: [ 1356.079387] palimpsest[6817] general protection ip:7f2a2f8c7240 sp:7fff627e2010 error:0 in libgobject-2.0.so.0.2200.3[7f2a2f89c000+44000]
Jeg begynder at få lyst til at geninstallere men det er lige blevet besværliggjort en hel del pga af manglende usb-backup.
EDIT 4: Jeg har testet på en LiveCD også med ubuntu 9.10. Det fungerer helt fint: Her er sysloggen når jeg sætter usb-drevet til, til sammenligning:
